Abstract

PROBLEM TO BE SOLVED: To enhance reliability against temperature rise while cleaning outdoor air compactly by disposing a passage on the air supply side following to a heat exchanger on the under side of an inner air exhaust passage in the inner air exhaust passage and an outdoor air introducing passage. SOLUTION: The heat exchanging ventilator 10 is disposed indoors while communicating with outdoor through an outdoor inlet 34 and an exhaust opening 34. Air is fed from the air inlet 34 through an interconnecting opening 46 to a dehumidification mechanism 42 thence fed to each room through an air outlet 48. Passage on the air supply side following to a heat exchanger 20 is disposed on the under side of an inner air exhaust passage in an outdoor air introducing passage. Consequently, condensate from the heat exchanger 20 is collected in a drain pan 53 in an air supply passage utilizing pressure difference of air between an exhaust passage and the air supply passage. Furthermore, reliability is enhanced because an electric component box 55 for driving a deodor filter 24 and a ventilation fan 26 is disposed in the passage following to a heat exchanger 20 and the electric components are cooled with heat exchanged low temperature outdoor air.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

FIGS. 1A and 1B are a schematic diagram (a) and a perspective view (b) showing a heat exchange type ventilating apparatus according to Embodiment 1 of the present invention.

The housing of the heat exchange type ventilator 10 comprises a first housing 13 and a second housing 41. Inside the first housing 13, an inside air discharge path for exhausting air sucked from an inside air intake port (first intake port) 30 communicating with the room to the outside through an exhaust port 32, and a middle of the inside air discharge path. An inside air discharge fan 25 provided and an outside air intake port (second intake port) communicating with the outside of the room.
A part of the outside air introduction path (first outside air introduction path) for sending outside air sucked from the outside air to the communication port 46, an outside air introduction fan 26 provided in the middle of the outside air introduction path, the outside air introduction path, and the inside air discharge. Heat exchanger 2 arranged at the intersection of the route
0 is provided. In the second housing 41, a part of the outside air introduction path (second outside air introduction path) for supplying the outside air introduced from the communication port 46 into the room through the air supply port 48, the compressor 44, and the dehumidifying device. A dehumidifying mechanism 42 having a heat exchanger 45 and a fan 43 is provided. The first housing 13 and the second housing 41 each have a wall-mounted rail 50, and a cushioning material 51 is attached to a connection portion. Also, using the wall-mounted mounting rail 52, the first
The housing 13 and the second housing 41 can be installed on a wall.

The heat exchange type ventilator 10 of the present invention is installed at an appropriate position indoors, communicates the outside air intake port 34 and the exhaust port 32 to the outside through appropriate pipes, and connects the inside air intake port 30 and the air supply. The port 48 communicates with the room through a suitable pipe. still,
There are usually a plurality of rooms for ventilation, and indoor piping is generally long, so the inside air intake port 30 and the air supply port 48 are
It is preferable to provide a plurality of locations as shown in the figure.

The air (indicated as RA in the figure) drawn from the room to be ventilated through the inside air inlet 30 is supplied to the heat exchanger 20.
And is exhausted to the outside from the exhaust port 32 (E in the figure).
A). On the other hand, air (indicated as OA in the figure) drawn in from outside through the outside air intake port 34 passes through the heat exchanger 20 and is sent out from the communication port 46. Each forced air flow is controlled by the inside air exhaust fan 25 and the outside air introduction fan 26.
Secured by The types of the outside air introduction fan 26 and the inside air discharge fan 25 are not particularly limited as long as necessary ventilation volumes can be secured. It is desirable that the ventilation rate be such that the air in the house is replaced about 0.5 times per hour. If the amount of ventilation is too large, heat loss in the room will be large, and if it is too small, ventilation will be insufficient. For example, in the case of a general house, it is desirable that the ventilation is about 180 m3 / h. Further, it is preferable that the air volumes of the inside air discharge fan 25 and the outside air introduction fan 26 can be adjusted according to the size of the house.

In the heat exchanger 20, by performing heat exchange between the outside air and the room air, the temperature difference between the introduced outside air and the room is suppressed. For example, an outside air temperature of 35 ° C. and an indoor temperature of 25 ° C.
° C and the capacity of the heat exchanger 20 is 50%,
The temperature of the outside air introduced can be about 30 ° C.
Note that the heat exchanger 20 is preferably a sensible heat type heat exchanger that exchanges only the temperature. This is because, in the case of a total heat type heat exchanger that exchanges both temperature and humidity, odor accumulation becomes a problem as described above.

The air introduced through the outside air supply port 34 is sent to the dehumidifying mechanism 42 through the communication port 46. The air introduced into the dehumidifying mechanism 42 is dehumidified by passing through the dehumidifying heat exchanger 45, and is then sent out to each room through the air supply port 48 (indicated as SA in the figure).

In the heat exchange type ventilator 10 of the present invention, the dew condensation water from the heat exchanger 20 is provided by arranging the path on the air inlet side after the heat exchanger in the outside air introduction path below the inside air discharge path. Can be stored in the water tray 53 of the air supply path without using the pressure difference between the air in the discharge path and the air supply path to store dew. Further, from this configuration, a space volume of an air supply path can be taken, and a deodorizing filter 24 for purifying air and an electric component box 55 for driving a ventilation fan 26 are arranged in a path subsequent to the heat exchanger. Can be cooled, so that a highly reliable electrical box mounting structure can be obtained. In addition, the main body can be configured without making the main body horizontal, and devices such as a dehumidifying mechanism can be connected to the side of the ventilation main body.

Also, as shown in FIGS. 2 (a), 2 (b) and 2 (c), since the water receiving tray 54 is disposed in the inside air discharge path, the low outside air temperature and the room temperature exchange temperature in winter and the room discharge is performed. Even if the air becomes 100% relative humidity and the wind circuit becomes condensed after the heat exchanger, dew water treatment can be performed reliably. Since the water receiving tray 54 is located on the lower surface of the wind circuit and is directed to the lower surface of the blower, there is an effect that all dew water after the heat exchanger can be treated. Further, the drain port 56 for the dew condensation water treatment is located at the lower end of the inclined groove at the end of the water receiving tray 54, so that drain water discharged can be easily treated. Further, since the drain port 56 is in the back foam 58, the water from the drain port 56 foams and enters the lower water receiving tray 53. By this water treatment, the water can be treated without being scattered by the wind of the outside air introduction path.

Also, as shown in FIG. 3 (a), by disposing the water receiving tray 53 in the outside air introduction path, the temperature of the outside air having a high humidity and the room air cooled in the summer are exchanged, and the outside air introduction air is relatively changed. Even if the humidity becomes 100% and the wind circuit becomes condensed after the heat exchanger, dew water treatment can be performed reliably.

As shown in FIG. 3A, the water receiving tray 53 disposed on the outside air introducing path and the water receiving tray 54 disposed on the inside air discharging path are disposed on the lower projection surface of the heat exchanger 20 so that the heat is removed. There is an effect that the dew water dropped from the exchanger 20 can be reliably received and water treatment can be performed.

As shown in FIG. 3 (b), by providing a drainage plate 57 for dew condensation water on the lower surface of the water receiving tray 54 disposed in the inside air discharge path, the outside air having a high humidity and the room air cooled in the summer can be provided. Condensation water is generated in the outside air introduction route due to heat exchange,
There is an effect that water treatment can be performed without water drops condensed on the water receiving tray being blown off by the wind of the outside air introduction path. If the drain plate 57 is not provided, the dew condensation water may move rightward on the downwind side of the lower surface of the water tray 54 and may not enter the water tray 53 on the outside air introduction path.

[0027] Further, since a portion from the intake port of the inside air discharge path to the inside air discharge path and a portion from the second intake port of the outside air introduction path to the outside air supply path for supplying air into the room is formed of a heat insulating material, the outside air is formed. It has the effect of limiting the locations where dew is formed due to the temperature difference between the air and the room air to ensure water treatment and to suppress dew condensation on the main body.

Also, as shown in FIG. 1 (a), the electrical component box 55 is disposed after the heat exchanger in the outside air introduction path, so that the cooling effect by flowing a large amount of air through the electrical components and the cooling of the heat exchanger. Since it is the later wind and not the direct outside air, the wind having a relatively low temperature passes therethrough, so that there is an effect that the reliability with respect to the temperature of the electrical component is increased.

Also, as shown in FIG. 1B, the two units are hooked on one mounting bracket so that another unit comes into contact with the air supply port of the outside air introduction path, so that the positional relationship between the two units is determined and the compactness is achieved. There is an effect that can be arranged in.

[0030]

The present invention has the following effects because it is configured as described above.

According to the first aspect of the present invention, in the outside air introduction path of the inside air discharge path and the outside air introduction path, the path on the air supply port side after the heat exchanger is located below the inside air discharge path. By arranging it on the side, the main body can be made compact without being elongated horizontally, and the outside air introduction path can be lengthened, so that the electrical components and the outside air cleaning filter can be arranged in that space.

According to the second aspect of the present invention, the water receiving tray is arranged in the inside air discharge path and the drain port is set at the end, so that the dew water treatment in the winter operation can be performed. Further, by providing the drain port at the end, there is an effect that the condensed water in the inside air discharge path can be surely flown to the lower water tray.

According to the third aspect of the present invention, since the water receiving tray is arranged in the outside air introduction path, dew water treatment in summer operation can be performed.

According to the fourth aspect of the present invention, since the water tray disposed on the outside air introduction path and the water tray disposed on the inside air discharge path are disposed on the lower projection plane of the heat exchanger, This has the effect of reliably treating the condensed water.

According to the fifth aspect of the present invention, the dew condensation plate is provided on the lower surface of the water tray disposed on the inside air discharge path, so that the water condensed on the water tray on the inside air discharge path can be removed from the outside air. There is an effect that dew water treatment can be performed without causing water splash in the introduction route.

According to the sixth aspect of the present invention, the outside air introduction path for supplying air to the room from the intake port of the inside air exhaust path to the inside air exhaust path and from the second intake port of the outside air introduction path to the room. The formation of the heat insulating material before the heat treatment has the effect of suppressing the occurrence of dew condensation and ensuring the water treatment.

According to the seventh aspect of the present invention, since the electrical component box is disposed after the heat exchanger in the outside air introduction path, the operation can be safely performed without being affected by the dew water from the heat exchanger. it can. In addition, there is an effect that a highly reliable electrical component box mounting structure can be formed at a low temperature.

According to the eighth aspect of the present invention, an installation space of the main body is reduced by hooking on one mounting bracket so that another unit comes into contact with the air supply port of the outside air introduction path. There is an effect that the wind circuit positional relationship with another unit can be easily fixed.
